QUESTION 131An engineer has performed a post-deployment site survey and noticed that access points were installed in suboptimal locations due to physical restrictions and obstacles. Which action must the engineer take to resolve this deployment issue?

A. Set DCA Channel Assignment Method to freeze.B. Set all Auto RE parameters to factory defaultC. Set TPC maximum and minimum power levels.D. Set static channels on all AP radios.

QUESTION 133A wireless engineer is configuring VoWLAN on a WLC.Which configuration should be implemented on the router or switch that is connected to the WLC?

A. The interface on the switch or router should trust the CoS settings of the WLC.B. The interface on the WLC should mark all packets as EF.C. The interface on the switch or router should strip all CoS markings on the IEEE 802.11 header.D. The interface must be configured as a Layer 3 interface.

Answer: AExplanation:We recommend that the QoS policy on the router/switch interfaces connected to the WLC be set to trust the CoS settings of the WLC. This means that the wired network responds to the CoS values controlled by the QoS policy set on the WLC. The WLC does not enforce any policy that changes the WLAN client DSCP values. The WLC policy effects will only be seen in the CoS values associated with the WLAN client traffic. If the routers and switches connecting to the WLC are set to trust DSCP, then a DSCP policy must be created and maintained on those router and switch interfaces–in addition to the policies applied on the WLC. For more information on WLAN QoS and traffic classification, refer to the Chapter 3, “Voice over WLAN Radio Frequency Design.”https://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Mobility/vowlan/41dg/vowlan41dg-book/vowla n_ch8.html

QUESTION 134A customer is preparing to deploy a wireless network in a stadium and is identifying coverage area requirement for the patrons in suite areas.Which two attributes are relevant to determining these coverage requirements? (Choose two.)

QUESTION 135Which purpose of using Metageek Chanalyzer during site survey is true?

A. to verify the antenna pattern of the APsB. to show only the usage of the 2.4 GHz spectrumC. to determine the sources of non-802.11 interferencesD. to verify the different channels used during the design of Wi-Fi networks

A. briefly during the predictive site surveyB. briefly during the passive site surveyC. for an extended period of time during the predeployment site survey and during the post-deployment site surveyD. for an extended period of time during the predeployment site survey only

Answer: C

QUESTION 137After installation of a new data-only wireless network, an engineer found that RRM has set all of the APs to a power level of 1.Which option describes the reason for this?

A. APs are too far apart for the set data rates.B. EORRM is enabledC. High co-channel interference exists.D. DTPC value is set too high.

Answer: A

QUESTION 138An engineer has performed a post-installation site survey using Ekahau Site Survey with a recommended adapter.Which two metrics can be different between the adapter used to survey and the client adapter? (Choose two.)

A. SNRB. data rateC. DFSD. channel overlap

Answer: ABExplanation:You must take note on what adapter was used in a site survey. The adapter should have similar characteristics to the adapters on the devices that are actually to be used in the wireless network. You should always verify what type of client adapter was used throughout the survey. A client adapter with a better receiver sensitivity and stronger antenna does not provide accurate results to compare against clients that are actually used in production.
